<P>[Moved to DR at the November, 2014 meeting.]</P>

<P>Paragraph 5 of 9.6.1 [<A href="https://wg21.link/dcl.fct.def.general">dcl.fct.def.general</A>] says,</P>

<BLOCKQUOTE>

A <I>cv-qualifier-seq</I> or a <I>ref-qualifier</I> (or both) can be part
of a non-static member function declaration, non-static member function
definition, or pointer to member function only
(9.3.4.6 [<A href="https://wg21.link/dcl.fct">dcl.fct</A>]); see _N4868_.11.4.3.2 [<A href="https://wg21.link/class.this">class.this</A>].

</BLOCKQUOTE>

<P>This is redundant with the specification in 9.3.4.6 [<A href="https://wg21.link/dcl.fct#6">dcl.fct</A>] paragraph 6
and is factually incorrect, since the list there contains
other permissible constructs.  It should be at most a note or possibly
removed altogether.</P>

<P><B>Proposed resolution (February, 2014):</B></P>

<P>Change 9.6.1 [<A href="https://wg21.link/dcl.fct.def.general#5">dcl.fct.def.general</A>] paragraph 5 as follows:</P>

<BLOCKQUOTE>

<DEL>A <I>cv-qualifier-seq</I> or a <I>ref-qualifier</I> (or both) can be part
of a non-static member function declaration, non-static member function
definition, or pointer to member function only
(9.3.4.6 [<A href="https://wg21.link/dcl.fct">dcl.fct</A>]); see _N4868_.11.4.3.2 [<A href="https://wg21.link/class.this">class.this</A>].</DEL>
<INS>[<I>Note:</I> a <I>cv-qualifier-seq</I> affects the type of
<TT>this</TT> in the body of a member function; see
9.3.4.3 [<A href="https://wg21.link/dcl.ref">dcl.ref</A>]. &#8212;<I>end note</I>]</INS>
